Thread: Mid range tang rear sights ?

Is there anyone handy in Christchurch or Canterbury who is running a rifle with a mid range tang rear sight that I could have a look at to see if they are a realistic option for my 55 year old eyes ?

Looking at buying a rifle ( can't view it ) with them fitted and want to see if I could use it as is ?
Or would need to fit something else which would effect what I would be prepared to spend

Cheers
